Answer the answer is d = 2
Step-by-step explanation:
Well, the sum of all internal angles in a triangle, isosceles or whatever else, is always 180°, so the sum of all those three folks, will be 180 then
so.. hmmm let's say the smallest angle is "a" units
twice that is, 2*a, or 2a
25 larger than that? is well 2a + 25
so... the other two twin angles, are 2a+25 each
thus a + (2a + 25) + (2a + 25) = 180
solve for "a" to find the smalles one
what about the twins? well, each is 2a + 25
Answer:
x = 3
Step-by-step explanation:
We need it in factorized form to get x.
If the quadratic equation can be divided by a-2 the first part is:
(a-2)
Now to get a², the a must be multpilied by itself. So
(a-2)(a)
To get -10, -2 must be multiplied by 5. So:
(a-2)(a+5)
we can expand to get x
a² + 5a - 2a -10
a² + 3a - 10
a² + ax - 10
x = 3
3*x+3*12
3x+36
You just need to do the multiplication separately !
Answer:
12
Step-by-step explanation:
The 6 part of the ratio represents 36 tomatoes.
Divide 36 by 6 to find the value of one part of the ratio
36 ÷ 6 = 6 ← value of 1 part of the ratio, thus
number of bananas = 2 × 6 = 12
